Description

Walking stick

Technical field

The present invention relates to a kind of walk helper, i.e. walking stick.

Background technology

A kind of walk helper such as walking stick, comprises linear or the rectilinear cane body of cardinal principle, and the one end is to comprise the upper end of holding support section, and the other end is the lower end that is provided with antislip metal packet header.

Walking stick mainly contains two shortcomings, and the first need to bend over from ground it to be picked up when walking stick falls, and is if the user does not want to allow it fall on ground on the other hand, must find vertical plane to support by it.

Present known walking stick comprises, the lower end ferrule has discoid widening on it, and this disk is coaxial with walking stick, in order to consist of a lever, when walking stick is applied on this disk with substantially vertical pressure on the ground like this, walking stick is rebounded.

But the shortcoming of this class walking stick is in whole operating period, to need the crucial power that applies or control, so that walking stick rebounds, yet the upright process of walking stick is suddenly, fast, and the user may catch when it uprightly rises, and great majority need all right moving inconvenience of people of walking stick.

Another known walking stick comprises the parts that walking stick is kept upright constantly, such as the walking stick of describing among the EP 0661010.The lower end of this walking stick is provided with an element, and this element has the convex surface that defines the point of rotation in bottom surface and periphery, and simultaneously, because a briquetting being arranged, the center of gravity of walking stick is positioned at the below of this point of rotation.

Such walking stick can uprightly rise voluntarily, and keeps plumbness constantly.But the practice confirmation, the size of its bottom makes its practicality of having lost basic function, as helping walking.

Another known walking stick has the stability that can guarantee in use, need not any support and can make its position of being kept upright.This class walking stick, such as among US 5992434, FR 2668690, DE 20309568 and the WO 99/35930 record, comprise the ferrule of stopping the plane that has that the end arranges, this plane is vertical with the main shaft of walking stick.

Although the walking stick described in these files has following feature: can guarantee on the one hand the stability when walking stick uses, guarantee on the other hand need not to support the position of can being kept upright, however, they still have shortcoming.In fact, in the situation that plan to erect walking stick or need not to support when being kept upright with pin, the action when its planar base surface requires operation is very accurate, so that the complete kiss the earth of this planar base surface, avoids rocking etc. and causes inclination.

Summary of the invention

The object of the present invention is to provide a kind of walking stick that can overcome above-mentioned various shortcomings.

Walking stick of the present invention comprises: a linear or substantially rectilinear cane bar, one comprises the upper end of holding support handle, with a lower end that is provided with antislip metal packet header, it has discoid widening, described disk is coaxial with walking stick, in order to consist of a lever, can rebound after exerting pressure thereon, it is characterized in that, described cane bar and described handle all adopt light material to make, described ferrule comprises a briquetting, make the center of gravity of walking stick as far as possible near the lower end, and described ferrule has the convex end wall.

Center of gravity is arranged near the lower end as far as possible, again in conjunction with discoid ferrule, so that walking stick rebounds after having applied pressure at the edge of ferrule, need not the crucial power that applies or to the specific control of this power.

Center of gravity is rebounded automatically because of the low not walking stick that can't make when walking stick is put on the ground, but enough low to assist to rebound walking stick, to guarantee the rebounding stability when further guaranteeing vertically to place with the certain tilt angle with respect to horizontal line.

Comparing to have the often difficult planar base surface of looking for of a settling position and described position, and the convex of the end of ferrule can be by providing a plurality of settling positions to slow down the action of rebounding.

According to another feature of walking stick of the present invention, the end wall of ferrule is the spherical caps shape.

According to an again feature of walking stick of the present invention, ferrule has to the peripheral wall of the diminishing truncate shape in end.

According to the another feature of walking stick of the present invention, the top edge of peripheral wall is connected with the cane bar by horn-like mid portion.

From the angle of making, cane bar and handle adopt composite to make, and are fibre reinforced plastics, such as glass fiber reinforced polycarbonate.

Ferrule adopts cast iron to make, and forms the briquetting with the elastomer parcel, but better and more favourable way is that briquetting is comprised of the battery that is used for the electronic installation of operation setting on walking stick, such as location and/or counting equipment.

Hereinafter pass through explanation, and cooperate the accompanying drawing of expression non-limiting example, make the advantage of walking stick provided by the invention and feature clearer.

Description of drawings

In the accompanying drawing:

Fig. 1 is the front view according to walking stick provided by the invention.

Fig. 2 is longitudinal cross-section, the centre position schematic diagram of the part of described walking stick.

Fig. 3 a, 3b, 3c, 3d are that the part of described walking stick is at the front view of different operational phases.

The specific embodiment

As shown in Figure 1, mainly comprise a linear or 10, one upper ends 11 that formed by hook-shaped handle of substantially rectilinear cane bar according to walking stick 1 of the present invention, and a ferrule 2 that is arranged on lower end 12.

Ferrule 2 is and coaxial discoid of cane bar 10 that its diameter is more much larger than cane bar 10, in order to strengthen as far as possible circumferential area, plays the effect of lever.

As shown in Figure 2, can see the lower end 12 of walking stick 1 and the detail of ferrule 2.

Ferrule 2 has the end wall 20 of slight bending, for having the spherical caps shape than larger radius of curvature, peripheral wall 21 is diminishing truncate shape to the end, and namely the top edge 23 of peripheral wall 21 forms a circle, the diameter of a circle that its diameter forms greater than this wall lower edge 24.

Further, the top edge 23 of peripheral wall 21 and the coupling part between the cane bar 10 are horn-like mid portion 25.

Ferrule 2 is mainly formed by the briquetting 3 of parcel one deck elastomeric material 22, namely forms

wall

20,21.

Briquetting 3 is used for the center of gravity of walking stick 1 is reduced to lower end 12 as far as possible.Briquetting can be comprised of metal material such as cast iron, preferably adopts the battery of the electronic installation that walking stick carries.

In fact, can provide walking stick positioner, alarm signal dispensing device or other various measurement mechanisms, such as pedometer, in walking stick.

With reference to figure 3a, 3b, 3c and 3d, the purposes of visible walking stick 1 each feature of the present invention.

As seen, when pressure P applies, as use pin in figure, in the time of on ferrule 2, use the latter as lever, the lower end 12 of walking stick 1 is in the situation of its three successive stages that rebound.

As shown in the figure, the center of gravity G of walking stick 1 is positioned at cane bar 10 near the height of lower end 12, and the position of this center of gravity G is depended on the length of cane bar 10 certainly, also depends on the material of cane bar 10 and handle 11, and the size of unshowned briquetting 3 and character.

In Fig. 3 a, walking stick 1 is by being placed on the S of ground, and 11(is not shown in the top) and ferrule 2 between, or more specifically, the 23 corner angle points that form at the edge.

In Fig. 3 b, by the P that exerts pressure at the top of ferrule 2, with the part of the ground S contact height along the part at the relative edge 23 of diameter, cane bar 10 is risen by leverage.

By with ferrule 2 along the edge 23 axial-rotations, until the ferrule 2 in the phase I props up ground S by its peripheral wall 21, realize rebounding.

In Fig. 3 c, by the P that exerts pressure, make the corner angle axial-rotations of cane bar 10 24 formation along the edge, and then the 10 continuation risings of cane bar, until wall 20 kiss the earth S, as shown in Fig. 3 d.

Center of gravity G is arranged near ferrule 2 so that walking stick 1 is easy to handle, and applied pressure minimizes, thereby reduce the cantilever impact, the control of being convenient to promote.

It should be noted, horn-like mid portion 25 provides with the pin certain comfortableness of P of exerting pressure.

Further, because the setting of the position of center of gravity G and the larger radius of curvature of wall 20, so walking stick 1 need not any surface against protecting the upright position.

The convex of wall 20 can make walking stick 1 be stabilized in the position of balance, and needn't be necessarily corresponding to the up rightness of cane bar 10.

Therefore, after the training, the walking stick of the present invention 1 that the user just can will fall on ground rebounds, and it is in vertical position, and holds it in this position, and need not for the user to operate with hand a little.
